curs_insch(3X)                                                                                curs_insch(3X)



NAME
       insch, winsch, mvinsch, mvwinsch - insert a character before cursor in a curses window

SYNOPSIS
       #include <curses.h>

       int insch(chtype ch);
       int winsch(WINDOW *win, chtype ch);
       int mvinsch(int y, int x, chtype ch);
       int mvwinsch(WINDOW *win, int y, int x, chtype ch);

DESCRIPTION
       These  routines insert the character ch before the character under the cursor.  All characters to the
       right of the cursor are moved one space to the right, with the possibility of the rightmost character
       on the line being lost.  The insertion operation does not change the cursor position.

RETURN VALUE
       All  routines  that return an integer return ERR upon failure and OK (SVr4 specifies only "an integer
       value other than ERR") upon successful completion, unless otherwise noted in  the  preceding  routine
       descriptions.

NOTES
       These routines do not necessarily imply use of a hardware insert character feature.

       Note that insch, mvinsch, and mvwinsch may be macros.

PORTABILITY
       These functions are described in the XSI Curses standard, Issue 4.

SEE ALSO
       curses(3X).

       Comparable functions in the wide-character (ncursesw) library are described in curs_ins_wch(3X).
